1. A gastro-occlusive device, comprising:
- a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude at least 50% of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that is at or in interior proximity to a dermal wall of the patient'"'"'s body or extends exteriorly out of the dermal wall of the patient'"'"'s body;
means for selectively inflating the balloon, coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least 50% of the volume of the stomach cavity;
first and second stomach wall positional anchoring members for the gas tube, the first and second positional anchoring members being adapted for placement along inner and outer surfaces, respectively, of a stomach wall of the patient; and
first and second dermal wall positional anchoring members for the gas tube, the first and second dermal wall positional anchoring members being adapted for placement along outer and inner surfaces, respectively, of the dermal wall;
wherein spacing is provided between said second stomach wall positional anchoring member and said second dermal wall positional anchoring member with a section of the gas tube extending therebetween to allow occurrence of normal movement of the stomach wall and normal movement of the dermal wall relative to one another adjacent to the stomach wall positional anchoring members and dermal wall positional anchoring members.

Abstract
A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending outwardly through a stomach wall for coupling with a gas source for selectively inflating the balloon, to occlude at least a portion of the volume of the stomach cavity. The gastro-occlusive device may be employed in combination with a feeding tube unit, a drain unit or other ancillary apparatus, and is useful for treatment of morbid obesity and various eating disorders.

12. A method of treating a subject in need of treatment for an eating disorder or overweight condition, said method comprising disposing in the stomach of the subject a balloon that is inflatable to occlude at least 50% of interior volume of the stomach, wherein the balloon is coupled by a tube defining a gas flow passage to an actuatable source of inflation gas, and actuating the source of inflation gas to flow gas into the balloon for inflation thereof to occlude at least 50% of the interior volume of the stomach, to an extent producing satiety with reduced intake of nutrition, relative to a corresponding subject lacking the inflated balloon in the subject'"'"'s stomach, wherein the stomach is defined by a stomach wall, said gas flow passage is at or in interior proximity to a dermal wall of the subject'"'"'s body or extends exteriorly out of the dermal wall of the subject'"'"'s body, wherein the tube is anchored to the stomach wall with first and second stomach wall positional anchoring members adapted for placement along inner and outer surfaces, respectively, of the stomach wall;
- wherein the tube is anchored to the dermal wall with first and second dermal wall anchoring members disposed along outer and inner surfaces, respectively, of the dermal wall;
wherein spacing is provided between said second stomach wall positional anchoring member and said second dermal wall positional anchoring member with a section of the tube extending therebetween, with the spacing allowing occurrence of normal movement of the stomach wall and normal movement of the dermal wall relative to one another adjacent to the stomach wall positional anchoring members and the dermal wall positional anchoring members. - View Dependent Claims (13, 14, 15, 16, 17)
- wherein the tube is anchored to the dermal wall with first and second dermal wall anchoring members disposed along outer and inner surfaces, respectively, of the dermal wall;

18. A gastro-occlusive device, comprising:
-
a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude at least 50% of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that is at or in interior proximity to a surface of the patient'"'"'s body or extends exteriorly out of a dermal wall of the patient'"'"'s body; means for selectively inflating the balloon, coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least 50% of the volume of the stomach cavity; an inner stomach wall positional anchoring member for the gas tube, said inner stomach wall positional anchoring member being adapted for placement along an inner surface of a stomach wall of the patient; an outer dermal wall positional anchoring member for the gas tube, said outer dermal wall positional anchoring member being adapted for placement along an outer surface of the dermal wall; and at least one additional positional anchoring member including any of (i) an outer stomach wall positional anchoring member for the gas tube, said outer stomach wall positional anchoring member being adapted for placement along an outer surface of a stomach wall of the patient, and (ii) an inner dermal wall positional anchoring member for the gas tube, said inner dermal wall positional anchoring member being adapted for placement along an inner surface the dermal wall; wherein spacing is provided between the stomach wall and the dermal wall adjacent to said at least one additional positional anchoring member, with a section of the gas tube extending between the stomach wall and the dermal wall to allow occurrence of normal movement of the stomach wall and normal movement of the dermal wall relative to one another adjacent to the at least one additional positional anchoring member. - View Dependent Claims (19)

20. A method of treating a subject in need of treatment for an eating disorder or overweight condition, said method comprising disposing in the stomach of the subject a balloon that is inflatable to occlude at least 50% of interior volume of the stomach, wherein the balloon is coupled by a tube defining a gas flow passage to an actuatable source of inflation gas, and actuating the source of inflation gas to flow gas into the balloon for inflation thereof to occlude at least 50% of the interior volume of the stomach, to an extent producing satiety with reduced intake of nutrition, relative to a corresponding subject lacking the inflated balloon in the subject'"'"'s stomach;
-
wherein the stomach is defined by a stomach wall, said gas flow passage is at or in interior proximity to a dermal wall of the subject'"'"'s body or extends exteriorly out of the dermal wall of the subject'"'"'s body; wherein the tube is anchored to the stomach wall and the dermal wall via elements including (A) an inner stomach wall positional anchoring member arranged along an inner surface of the stomach wall, (B) an outer dermal wall anchoring member arranged along an outer surface of the dermal wall, and (C) at least one additional positional anchoring member including any of (i) an outer stomach wall positional anchoring member arranged along an outer surface of the stomach wall and (ii) an inner dermal wall positional anchoring member arranged along an inner surface of the dermal wall; and wherein spacing is provided between the stomach wall and the dermal wall adjacent to said at least one additional positional anchoring member, with a section of the tube extending between the stomach wall and the dermal wall to allow occurrence of normal movement of the stomach wall and normal movement of the dermal wall relative to one another adjacent to the at least one additional positional anchoring member.
